This study used untargeted metabolomics, sensory assessment (E-eye, E-nose, E-tongue), and antioxidant activity evaluation to investigate compositional changes and their effects. In the metabolomics analysis, a total of 101 non-volatile and 306 volatile differential metabolites were identified.

A β-cyclodextrin-based supramolecular photonic crystal hydrogel biosensor with macroporous structures for naked-eye visual detection of cholesterol.

Cholesterol (CHO) is an essential lipid in cell membranes and a precursor for vital living substances. Abnormal CHO levels can cause cardiovascular diseases. Therefore, simple and accurate monitoring of CHO levels is crucial for early diagnosis and effective management of cardiovascular diseases.

Attentional Rhythms Are Sensitive to Binocular Visual Pathway.

Visual attention is intrinsically rhythmic and oscillates based on the discrete sampling of either single or multiple objects. Recently, studies have found that the early visual cortex (V1/V2) modulates attentional rhythms. Both monocular and binocular cells are present in the early visual cortex, which acts as a transfer station for transformation of the monocular visual pathway into the binocular visual pathway.

A rapid, multiplexed and naked-eye readable paper assay for detecting heavy metal pollution in food using a catalytic colorimetric reaction.

Heavy metal contamination is a serious food safety issue. Herein, we report a rapid, multiplexed and naked-eye readable method for detecting heavy metal pollution in food samples using a cheap colorimetric paper, including milk. We leverage the urease catalysis reaction to amplify the presence of heavy metal ions, Hg and Pb, by exploiting their strong inhibitory effect on urease.

Mechanoreceptor Piezo1 channel-Mediated Interleukin Expression in Conjunctival Epithelial Cells: Linking Mechanical Stress to Ocular Inflammation.

Purpose: Mechanical stress on the ocular surface, such as from eye-rubbing, has been reported to lead to inflammation and various ocular conditions. We hypothesized that the mechanosensitive Piezo1 channel in the conjunctival epithelium contributes to the inflammatory response at the ocular surface after receiving mechanical stimuli.

Methods: Human conjunctival epithelial cells (HConjECs) were treated with Yoda1, a Piezo1-specific agonist, and various allergens to measure cytokine expression levels using qRT-PCR.

Senescent retinal pigment epithelial cells promote angiogenesis in choroidal neovascularization via the TAK1/p38 MAPK pathway.

Senescent retinal pigment epithelial cells play a key role in neovascular age-related macular degeneration (nAMD); however, the mechanisms underlying the angiogenic ability of these cells remain unclear. Herein, we investigated the effects of the senescent adult retinal pigment epithelial cell line-19 (ARPE-19) on wound healing, cell migration and survival, and tube formation abilities of human umbilical vein endothelial cells (HUVECs). Additionally, we used Brown Norway rats to establish a laser-induced choroidal neovascularization (CNV) model for further nAMD-related studies.

Mosaicism and intronic variants in RB1 gene revealed by next generation sequencing in a cohort of Spanish retinoblastoma patients.

Constitutional variants in the RB1 gene predispose individuals to the development of Retinoblastoma (RB) and the occurrence of second tumors in adulthood. Detection of causal RB1 gene variants is essential to establish the genetic diagnosis and to performing familial studies and counseling. In our cohort of 579 Spanish RB patients, 15% of cases suspected to have a genetic origin remained negative after traditional Sanger sequencing and Multiplex Ligation-dependent Probe Amplification (MLPA) of RB1 gene, likely due to the possibility of mosaicism or non-coding variants.

A deep dive into radiation keratopathy; Going beyond the current frontiers.

Radiotherapy is one of the conventional treatments for head and neck malignancies. Despite the implementation of protective measures to minimize the detrimental impact on healthy tissues surrounding the radiation site, radiation keratopathy remains a prevalent complication. We aimed to establish a mouse model of radiation keratopathy to characterize the pathophysiology of the disease and enable future identification of potential treatments.

Predicting Parkinson's Disease Using a Deep-Learning Algorithm to Analyze Prodromal Medical and Prescription Data.

Background And Purpose: Parkinson's disease (PD) is characterized by various prodromal symptoms, and these symptoms are mostly investigated retrospectively. While some symptoms such as rapid eye movement sleep behavior disorder are highly specific, others are common. This makes it challenging to predict those at risk of PD based solely on less-specific prodromal symptoms.

Methods: We used cross-sectional data from the Health and Retirement Study (N = 16,339) to assess healthcare utilization: hospital stay, nursing home stay, hospice care, and doctor visits. The respondents were classified into two cognition groups using the Langa-Weir approach.

Influence of lens thickness on the accommodative range in healthy eyes.

Background: The maximum accommodative range is a useful indication of visual function. It decreases with age, but the exact cause of this decrease is not fully understood. It is associated with the increasing rigidity of the lens and changes to the lens shape, as well as the geometry of the zonular attachments.

Attention modulates subjective time perception across eye movements.

Prior research has established that actions, such as eye movements, influence time perception. However, the relationship between pre-saccadic attention, which is often associated with eye movement, and subjective time perception is not explored. Our study examines the impact of pre-saccadic attention on the subjective experience of time during eye movements, particularly focusing on its influence on subjective time perception at the saccade target.

PIKFYVE deficiency induces vacuole-like cataract via perturbing late endosome homeostasis.

Phosphoinositide kinase, FYVE-type zinc finger containing (PIKFYVE) was recently identified as a causative gene for cataract. Pikfyve phosphatidylinositol phosphate kinase domain-deficient (pikfyve) zebrafish lens and PIKFYVE-inhibited human lens epithelial cells developed vacuoles, colocalized with late endosome marker RAB7. In this study, the pikfyvezebrafish with vacuole-like cataract underwent transcriptomic and proteomic analyses to explore the underlying mechanisms of vacuole formation.

An Anthracene-imidazoanthraquinone Conjugate Exhibiting Ratiometric Fluorescence Turn - On Behavior with CN- and F- Anions.

A new conjugate, 2-(4-(anthracen-9-yl) phenyl)-[1,2-d]imidazole-1H-anthraquninone (AQI) has been designed and synthesized as a molecular probe 4. The photophysical and electrochemical behavior of the probe in the absence and presence of different class of ions were examined in acetonitrile solution. The probe 4 with F- and CN- anions showed ratiometric fluorescence "turn - On" response due to variation in ICT processes.

Seeing in the Future - a Perspective on Combining Light with Chemical Biology Approaches to Treat Retinal Pathologies.

New concepts to treat eye diseases have emerged that elegantly combine unnatural light exposure with chemical biology approaches to achieve superior cellular specificity and, as a result, improvement of visual function. Historically, light exposure without further molecular eye treatment has offered limited success including photocoagulation to halt pathological blood vessel growth or low light exposure to stimulate retinal cell viability. To add cellular specificity to such treatments, researchers have introduced various biological or chemical light-sensing molecules and combined those with light exposure.

Positional obstructive sleep apnea in children prescribed continuous positive airway pressure therapy for obstructive sleep-disordered breathing.

Positional obstructive sleep apnea, in which there is a ≥ 2:1 predominance of obstructive events in the supine position, is a sleep-disordered breathing phenotype with a targeted treatment in the form of positional device therapy. We sought to determine the prevalence of positional obstructive sleep apnea in a cohort of children prescribed continuous positive airway pressure therapy, ascertain risk factors for the condition, and determine the associated continuous positive airway pressure treatment adherence rate. A retrospective cohort study of all children > 2 years old from a single tertiary paediatric centre prescribed continuous positive airway pressure therapy over an 8-year period was conducted.

Visual attention matters during word recognition: A Bayesian modeling approach.

It is striking that visual attention, the process by which attentional resources are allocated in the visual field so as to locally enhance visual perception, is a pervasive component of models of eye movements in reading, but is seldom considered in models of isolated word recognition. We describe BRAID, a new Bayesian word-Recognition model with Attention, Interference and Dynamics. As most of its predecessors, BRAID incorporates three sensory, perceptual, and orthographic knowledge layers together with a lexical membership submodel.
